Step 1: Arrange the numbers from least to greatest and find the number in the middle.

GIVEN: 73, 75, 63, 56, 80, 29, 54

Least to greatest

29, 54, 56, 63,** **73, 75, 80

There are 7 numbers (odd)

So, middle value is the median

median = 63

Step 2: Replace the number and find the new median

GIVEN: Replace 80 with 40 and find the new median.

29, 40, 54, 56, 63, 73, 75

n = 7 (odd)

Middle value is the median

The new median would be 56.

The median would decrease from 63 to 56.
